2nd International Conference on Mechanics of Biomaterials & Tissues
In December 2007 Elsevier will organise the 2nd International Conference on Mechanics of Biomaterials & Tissues (www.icmobt.elsevier.com). The aim of the conference is to provide a forum for the discussion of the modeling and measurement of deformation and fracture behavior in biological materials and in those materials which are used to replace them in the human body.
"Persistence of a pinch in a pipe" by L. Mahadevan, Ashkan Vaziri and Moumita Das
The response of low-dimensional solid objects combines geometry and physics in unusual ways, exemplified in structures of great utility such as a thin-walled tube that is ubiquitous in nature and technology.
Interfacial toughness and mode mixity
When I was a graduate student, I spent several months to measure interfacial toughness between metalic (Cu and Au) films and thick substrates(Si and Polycarbonate). My methods were bulge test (blistering test) and 4-point bending test. I had many problems such as making an initial crack(pre-cracking), changing load phase angle applied to specimens, preparing/patterning thin films, constructing my own test apparatus, etc. The biggest problem was to measure the interfacial toughness over a wide range of loading phase angle. For a bimaterial with a non-zero oscillatory index(epsilon), we don't know the phase angle for a minimum interfacial toughness beforehand. Therefore, we need to measure the interfacial toughness over a wide range of phage angle. For engineering purpose, we need a minimum interfacial toughness value for reliability design because this value will lead to a conservative design of systems.
A paper on developing stochastic micromechanical model for elastic properties of functionally graded material (FGM)
Given link is for a stochastic micromechanical model developed for predicting probabilistic characteristics of elastic mechanical properties of an isotropic functionally graded material (FGM) subject to statistical uncertainties in material properties of constituents and their respective volume fractions.

Some write-ups in mechanics
My googling today brought me to this treasure trove of write-ups in mechanics:
This site contains informal (usually rough draft) technical notes and tutorials on topics in mechanics. The sophistication is at the first or second year graduate level. These write-ups include:
Homework 1, problem 1 - Self description
I'm Francisco Thiago S. Aragao. Please call me Thiago. I'm currently enrolled at the University of Nebraska at Lincoln Civil Enginering Master's Program under the advisory of Dr. Yong-Rak Kim. I have also a minor course in Engineering Mechanics. Below I'm answering the questions from the Problem 1 of Fracture Mechanics' Assignment 1.

Journal publishers are pioneers of Web 2.0
Eric Mockensturm has just posted a publication agreement proposed by provosts of several universities. In structuring iMechanica, we have tried to avoid the question of open access, and simply asked the question what if all papers are already openly accessible. Many mechanicians have discovered iMechanica, and the registered users have recently passed 1000. Recent discussions of copyright on iMechanica have prompted Eric to post his entry, which has just led to this one.
